At JOYROOM, we built the JR-PBM08 20W Magnetic Wireless Power Bank (500mAh) for people who want a truly slim wireless power bank that feels effortless to carry and dependable to use. With a .9cm ultra-thin body—about as thin as a card—it’s an ultra slim power bank that fits comfortably in a pocket, clutch, or travel organizer without adding bulk.

The JR-PBM08 is designed for modern, on-the-go charging habits. Its auto-sensing magnetic wireless charging starts power delivery the moment you attach your phone, giving you a clean, cable-free experience. When you need maximum speed, switch to PD 20W wired fast charging (up to 3× faster than conventional chargers), while 15W wireless charging offers a convenient everyday option. With Type‑C bidirectional charging, you can recharge the power bank quickly and also fast-charge your devices from the same port.

To support safe, stable performance, we use an aircraft-grade aluminum shell to help dissipate heat efficiently, paired with smart temperature control to reduce overheating risk during charging. For flexibility across setups, the dual input ports (Type‑C and Lightning) make it easy to top up whether you’re carrying a USB‑C or Lightning cable. The result is a portable magnetic wireless power bank that balances compact design, fast charging, and travel-friendly reliability.
